"Those females that were grouped without males were better able to recognise one another
and also showed a preference for females from within, rather than outside, the group.
Dr Safi Darden adds: "The health and well-being of an individual is dependent, in part,
on having strong social bonds with others and females that have weakened social bonds
may be less likely to survive in the wild..
The researchers do not know exactly why sexual harassment from males
has such a marked effect on female social interaction.
However, it is possible that the sheer amount of time spent by females dealing with
unwanted male attention prevents them from forming relationships with other females",
